Reaction Steps

130 ml (0.13 moles) of a THF solution of 1M of ethylmagnesium bromide was dropped in a mixed solution of 43.3 g (10 mmols) of 1-chloro-4-(4-(trans-4-(3-fluoro-4-difluoromethoxyphenyl)cyclohexyl)butyl)-1-silacyclohexane and 30 ml of THF. The resultant product was found to be a mixture of trans and cis isomers with respect to the silacyclohexane ring. The product was subjected to ordinary aftertreatments, followed by isolation through chromatography to obtain 42.7 g (yield: 87%) of the intended trans isomer product.
